Not being able to check-in due to government regulations can also be because the international travel document by itself may appear to the airline as not being evidence by itself of the person being admissible. I can go into a rather humorous story about a flight a few days ago where this was the issue and the check-in reps started making stuff up about what is required for EU dual-citizens with valid EU country passports to be admissible to the EU, but it would just divert the discussion and do no one any good.

I am 100% certain that for US-bound international flights, more weeks than not, I see SSSS hits which are due to manual, computer-aided selection -- by the relevant government authorities -- and/or are due to the airline/airline security contractor. While such dynamic may or may not be a minority of the "random" or "non-random" SSSS hits, it happens routinely.
Most US-bound flights' airlines can't print a PreCheck boarding pass with SSSS on it from most foreign airports serving flights to the US -- and that is speaking of just PreCheck-eligible airlines from airports where PreCheck boarding passes are issued. I won't discuss this further, so don't ask.
